ENGINE DIES WHEN TURNING ???
Not sure why this happens but if I do a tight turn like a U turn the engine will just die ?
Has happened quite often and I am not sure why this would happen so anybody got a idea I am all ears

Well, a quick Google search for "2006 f150 power steering switch location" comes up w this, if the forum will allow a link to a competing forum:
https://www.f150forum.com/f4/power-s...switch-295560/
That is 2wd, no idea if 4wd is similar ---- BUT I can tell you what is similar is that they're always in the high pressure line somewhere.
'87-96 only the 302s got a PS pressure switch, the 5.8 never did & never needed one. I have NO idea if Ford followed this model w 4.6 vs 5.4 in later years. But again, your symptoms are precisely why PS pressure switches were installed so it's only an educated guess.

When the same thing was happening to my wifes 06 expedition I found it was the serpentine belt, it eventually blow clean off. Thought it was the power steering but it was the belt. I would check your belt make sure it's good.

A belt cannot cause the engine to stall. I would be more inclined to think the high pressure relieve valve for the power steering wasn't letting pressure off fast enough. This would cause the load from the power steering on the engine to increase dramatically. The two possible outcomes would be the engine stalling or the belt letting go.

Ah.. I just figured that maybe a possibility I know on my expedition that's what was going on with it months ago now it's a timing belt.

Power steering SWITCH ? Can not wrap my head around a switch? Trying to understand how a switch would work in this case as it appears that the stalling is caused by pressure not relieved when in hard lock position. I would think some kind of relief valve would be needed. Unless switch opens a valve somewhere?
Just spitballin . Maybe someone knows how that works.Smokie

Again, Google answers your question:
The Importance of Power Steering Oil Pressure Switches | FPS Distribution
"In some applications, the power steering oil pressure switch also feeds information about demand on the power steering system to the vehicle’s engine ECU. This allows it to manage engine speed during low-speed parking manoeuvres [sic]. An increase in demand on the power steering system means increased load on the engine. As these sort of manoeuvres usually occur when the engine speed is low, the engine ECU will need to increase the engine speed to compensate for these extra loads or the engine will stall. This is why the power steering pressure switch is an important part of the system."
Ever heard of idle-up switches for a/c compressor clutch engagement? SAME THING

I was going to say exactly the same thing, ran into this exact problem couple of times on multiple vehicles. Good advice.
